DAVID M. WESTON, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN LU BRICATORS.

Specification forming nurt of Letters Patent No. 41,335. dated January 19, 1864.

To all whom, 1125 may concern:

Be it known that I, DAVID M. WESTON, a resident of Boston, in the county otl Suffolk and State of Massachusetts, have invented a new and useful Mechanism for Lubricating the Journal of an Upright Shaft; and I do hereby declare lthe saine to be fully described in the following specilcation, and represented' in the accompanying drawings, of which- Figure 1 denotes a front elevation, and Fig. 2 a vertical section, of an upright shaft with my invention applied to it.

In the drawings, A denotes the shaft whose journal a extends through and is supported by a bearing, b, suitably supported. A stationary cup, B, is fixed on the top of' the bearing and encompasses the shaft and opens into the bearing.

Below the bearing b there is another cup or vessel, C, cylindrical in form and having an annular flange, c, projecting inward from the upper part of its periphery. A pipe, D, leading' outof the cup O and upward is bent over at or near its upper end so as to Vdischarge into ldie cup B7 that part of the pipe which is within the cup being curved around in the arc of a circle.

When there may be oil in the cup O, and such cup may be in rapid revolution with the shai't A, and in a direction toward the lower end of the pipe D, the centrifuga-l force generated in the oii will cause it to be thrown against the inner periphery of the vessel C, and from thence to ow upward through the pipe D and out of its upper end and into the cup B. From the said'cup B the oil will pass into and through the bearing,` b and back into the cup (J, from which it will be again forced up the pipe D and into the cup B. Thus the bearing, while the shaft may be in revolution, will continue to he lubricated with oil.

What I claim as my invention is The centrifugal oiling apparatus, composed of the cups B and O, and the pipe D, ar-

,ranged with respect to the shaft A and its bearing b, substantially in the manner and so as to operate as described.v
